Document Summary
Lumping some codes or computing conceptually targeted indices (ex. index of extent to which mothers are responsive to the gaze of their infants) - found to be useful and productive strategy for observational data (bakeman & gottman) Measuring change is difficult for both conceptual and statistical reasons as discussed in the article titled cross-sectional and longitudinal designs . What are key characteristics of cross-sectional studies discussed in the article? provide examples to explain these characteristics. There are different groups within a same sample. Groupings might include divisions by gender or social class, but usually involve comparisons between different age periods. In such designs individuals within different age groups are studied just once and any difference on a dependent measure is attributed to the hypothesized process of change between them. Differences between age groups only reveal differences and not the process of developmental change within the child.
